The “X” stands for “extreme.” That’s what Qualcomm’s marketing department wants you to think about the new Snapdragon 8cx.

It’s a brand-new processor for always-connected Windows laptops and 2-in-1 convertible PCs, and Qualcomm says it’ll the first 7nm chip for a PC platform, beating Intel to the punch. Qualcomm says it’s the biggest performance leap for a Snapdragon ever, with “amazing battery life,” and the company says it’ll also deliver up to 2Gbps cellular connectivity.

It’s the mobile chipmaker’s first purpose-built chip for Windows, instead of the tweaked smartphone chips it’s tried to squeeze into laptops before. “It’s a real PC, that can do real multitasking and productivity,” the company says.

Mind you, none of that necessarily means it’ll deliver “extreme” performance compared to rival laptop chips from Intel, Nvidia and AMD. We’re talking about laptops, not beefy gaming rigs. But this time, Qualcomm may have finally wrung enough power from its silicon to build a competent portable PC.

When it comes to graphics, Qualcomm says its new Adreno 680 Extreme GPU in the 8cx is twice as fast as the one in its previous Snapdragon 850 for Windows laptops — the one in Samsung’s recently-released Galaxy Book 2 and the Lenovo C630 WOS — and 60 percent more power efficient than that chip to boot. It can also support two 4K external monitors simultaneously, up from just one monitor before.
